eEsI IENr WHEEL.

I Application aieaaan a a1, 1920. Serial No. 355,315.

To all 'whOm it may concern? Be it known'that I, SAMUEL Gnossarsiv,

a citizen of the United States, and a resident of the city of New York, borough and county of the Bronx, and State of New York, have invented a certain new and useful Inip'roved Resilient WVheel, of which the following is a specification. f

The invention relatesto'wheelsfor automobiles and other vehicles,and, while being composed largely of' metal, will be resilien't to such a degree that vibrations due to road shocks and tractive and driving' forces will be taken up in the wheel and not be'transmitted 'to the body of the vehicle, and is of the same general type as that shown in my Patent No. 1,314,643, of September 2,1919, r v a r One object of the invention is to provide a wheel which will have the general appearance and riding qualities of one having a pneumatic tire, but which will not be subject "to punctures, blow-outs and other dangers to which pneumatic tires are subjected.

A further object is to produce awheel in which'the hub may be movable radially relatively to the rim or felloe, and in which the relatively movable elements may be lubricated. Y Y

A further object 'isto produce a simple and eflicient resilient wheel, which will be light in weight, strong and rigid in construction where rigidity is required, which may be easily assembled, and in which those elements which are rigidly secured together may be permanently atlixed as by welding. A still further object is to produce a solid tire of resilient material which may be readily affixed to thewheel, and which will not creep on the felloe. V A. further object is to provide means for enclosing the relatively movable parts of the tire, and for providing additional support for the tire.

" further object of the inventiomis t produce device of the character described,

which is extremely simple inconstruction, neat and attractive in appearance, thoroughly reliable and eflicientjn itsp'urpose, and inexpensive to manufacture.

.lVith these and other objects in view to be more fully set forth hereinafter, the invenof tire rim.-

tion consists in the novel construction, combination of elements, and arrangement of parts which Wlll beexemplified 1n the construction hereinafter described in the specification and illustrated in the accompanying drawings considered together or separately.

The inventive idea involved is capable of receiving a variety of mechanical expressions, some of which for thepurpose of illustrating the invention, are shown in the accompanying drawings.

The invention will be first describedin connection with the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views, and then more specifically defined and indicated in the appended claims.

sockets. The shells'may be secured to form an annular chamber as shown.

Carried within the hub chamber is 'a ring 5 concentric with the hub, and to the ring is secured a plurality of lradiating spoke members 6. Each spoke member is I socket by any suitable means; V

composed of a tubeandpasses through a socket in the, hub and may be held in the Intothe bore of each spoke 6 is a'cylin-V drical plunger 7 so fitted in the spoke as to be capableof free movement longitudinally thereof, A coil spring 8 is disposed in each spoke between the ring 5 and plunger and normally tends to move the latter outward- ,ly. The outer end of each plunger is pro- I 7 bolts 16.

structed and arranged that shearing strains 121.16 not put upon the bolts As shown in Fig. 1 the material of the run 12 is struck" up at each .end of a 'frame to form a protuberance or r dge 17 which will prevent V the box from creeping around the rim.

The bottom. of the frame is. convexed later ally of the box shown in Fig. 2 andfit's into a concave depression'in the rim to prevent movement of the frame axially'of the wheel. The bolts 16 arepreferably provided with screw heads countersunk in the rim 12' whereby the outer surface'of the lattermay -'-be flush.

I'desire .it distinctly understoodthat I do not limitmyself to the use of light weight bolts, but-that I can utilize bolts of sulficientrstrength to withstand any strain put upon them so as to eliminate the various .otherelements and combinations previously 'mentio-ned. f V

In Figs. 3, 1, 5, 6, 7, '8, 9, 10 and 11 are shown'various modified forms of the means for preventing relative movement of a'frame and the rim.fProvision is made, however.

for permitting more or less movement of nthe plungers' circumferentially-of the rim L 12 through, the cushioned connection-be 7 6O tween the outer-end of each plunger and the frame with which itcooperates as shown and described in detail in my patent above referred to; V Y Carried-on theouterends of the. spoke '6 is an annularchannelmember 18 spaced'a,

The ends of the spokes project a short distance beyondethe. channel ring 18 and each spokeis provided r with a nipple cap'19; The caps19 are pref? erably hardened steel and project. through theering 18; Each cap'is pro-vided with' an outwardly projecting flange 20 at one end,

and the said flange cooperates with the inner each cap is'provided with an inwardly pro surface of the ring 18. The outer end of jecting peripheral fiange21 which projects: 7

' The cap 19 is lastened preferablybyspot welding to the spoke "tube' 6 or ring 18 or both whereby a strong and rigid structure .will beproduced at a minimum cost. 7

A pair of annular cheek plates 22 are pro and not'on the comparatively soft tube 6 .may be made of ordinary i. no"

vided to enclose 'the'fs'pace between the tire rim 12and the channel ring 18 Frachcheek plate' compri'ses a, substantially flat ring" the inner diameter of :which is the sameas that of the ring 18 and the outer diameter is somewhat greater than that of the rim 12;

The cheek plate not onlyacts as a support for the rubber tire toholdi thelatter in place 7 V 7 and a'so to keep the dirt and water out, but I the said cheek,platesalso-a'ct as agreinforcing memberrto the rim-12, and by reason thereof it enables me to use lighter material; The outer edge of 1 each. cheek plate. is rolled to form air-annular bead 23 "for the purpose of giving addediri gidity mum plate 22 and theedge-of reach bead 23 is 7 adapted to engage'a. grooveor recess 24, one

on each sideo'l a solid rubber tire 25 which 1 is carried on the'rim 12.: The edges'o't the rim mare-preferably curved to fit-into the hollows of the-beads 23whereby the rim 12 and tire 25jwill derivegadditional support from thee-heel: plates The" edges of-the,

rim l 2 being enclosed'bythe cheek plates" will be protected from injurv, as will the inner edges of the tire.

Thecheek plates are sernredjtogetheriand 7 to the rim 12by means otbolts 26gdisposed, one between each pair otspokes; -Eaclr alternate bolt 26; passesthroughasbracketfll carried bythe'rim12. The brackets 27 may conveniently bemade of sheetinetal otthe form shown-with the base members28 weld ed orotherwise secured to the rim;12. The

bolts 26 pass freely throughathe brackets and the latter are tapered in shape as shown in Figs. 2 and 5. The inner end 29 of each bracket is of the samewidth as the rim 18.

while the outer end at the -base member 28 is somewhat narrower. By this construction when the bolts 26 are set up the outer edge of each cheek plate may be sprung inward to more or less compress the tire, but the inner edge of the cheek plates will not be clamped to the ri'ng18 whereby the rim 12 andtire 25' may-assume a position eccentric with the ring 18 and hub.

hen headed bolts 16. are employed as shownin Fig. 1, recesses 30 must be formed in the inner periphery of the tire 25, for. the reception of such heads. a A The hub may be filled with lubricating material by means ofan opening 36, which may be closed by any desired means, and the lubricant will be free to travel throughout the wheel. The clamping action of the cheek plates 22 against the curved edges of the rim '12 will prevent the lubricant from coming in contact with the rubber tire.

In accordance with the provisions of the patent statute, I have described the principle of my invention together with the apparatus which I now consider to represent the best embodiment thereof, but I desire it understood that my invention is not confined to the particular form of apparatus herein shown and described, the same being merely illustrative, and that the invention can be carried out in other ways without departing from the spirit of my invention, and therefore, I claim broadly the right to employ all equivalent instrumentalities coming within the scope of the appended claims, and by means of which objects of my invention are attained, and the new results accom-c plishcc. as herein set forth, as it is obvious that the particular embodiment herein shown and described is only one of many that can be employed to attain these objects and accomplish these results.
